Microsoft's Macintosh Business Unit (Mac BU) announced the official availability of Microsoft Office 2008 for Mac at the Macworld Conference and Expo 2008. You can buy the software online or in stores. Here is more info from the announcement:

"Office 2008 for Mac is significantly enhanced to provide a simplified user experience that helps beginners and longtime experts alike deliver professional documents that are compatible for co-workers and friends on Macs and PCs. The suite provides the Office tools Mac users rely on, with a Mac-like approach and style. In addition to Office 2008, the Mac BU Web site, Mactopia (http://www.microsoft.com/mac), features a dramatic transformation to provide an even more resourceful hub for all things Mac BU.

Key to Compatibility: Keeping Mac and PC Users ConnectedMac users require the ability to share their documents with confidence; they also need a consistent look to their output on both PCs and Macs. Office 2008 for Mac is the most compatible suite on the market, sharing core technologies with the 2007 Office system such as Open XML File Formats and the graphics engine, OfficeArt, to ensure consistency in graphics rendering when they are shared. Office 2008 for Mac is also compatible with earlier file formats so that users can continue to use the older DOC, XLS and PPT binary formats. The updated suite is Universal and runs natively on Intel- and Power PC-based Macs.

Office 2008 also makes great strides to meet the needs of users in cross-platform organizations. The most complete Exchange client on the Mac, Entourage 2008 in Office 2008 for Mac and Office 2008 for Mac Special Media Edition delivers improved reliability and time management tools with updates for calendar management and Out of Office Assistant to keep users connected and productive. IT managers also will benefit from new tools for customized deployment.

Increased Discoverability: The Tools You Need When You Need ThemOffice 2008 for Mac offers a streamlined and intuitive new user interface that lets users immediately jump in and start working. The updated suite keeps the traditional drop-down menus but adds the new Elements Gallery row of tools in Word, Excel and PowerPoint to unlock the power of Office. With the Elements Gallery, key features and functions are more discoverable and accessible so that users can efficiently tackle their work with the tools they need right at their fingertips. An example of the content in the Elements Gallery is Document Elements in Word 2008, which provides a thumbnail catalog of content and functions that simplify some common yet tedious tasks, such as inserting a table of contents or producing a professional-looking cover page.

Throughout the suite, users will find a revamped Toolbox that is now a true one-stop destination to find some of the most useful tools in Office for Mac: the Object Palette, Animation Settings and the new Citations function, which makes it a cinch to create citations and bibliographies. The Toolbox also features the contextual Formatting Palette, which adjusts its content for each application to truly make it more intuitive to create great-looking documents.

In addition, the new stand-alone My Day application allows users to track professional and personal priorities to stay on top of daily activities regardless of which application they are working in. Although My Day is connected to Entourage, users do not have to open the application to get a quick look at the day?s tasks, upcoming meetings and items on their To-Do List. When users do enter Entourage, they will enjoy a new simplified interface where they can customize the Toolbar, color-code their calendar appointments and easily add travel time to meetings.

Grows With You: The Perfect Product for Every UserFor a casual or seasoned user, Office 2008 for Mac provides the right tools to complete any project. Excel 2008 is a prime example, with new features for all users, even those with ?grid fear.? Ledger Sheets provide beginners with the prebuilt worksheets they need to easily master budgets, invoices and financial portfolios. Formula Builder walks users through the steps needed to confidently create accurate formulas. Advanced users can take on PivotTables and benefit from Formula AutoComplete, a drop-down menu that provides a variety of computation options. For power users, Excel 2008 introduces increased rows and columns that match the Windows-based 2007 Office system to ensure that users on Macs and PCs will have access to up to 16,000 columns and more than 1 million rows.

PowerPoint 2008 and Word 2008 both feature new design elements that give users as much help as they need. In either application, users can choose to start with a blank canvas or select from hundreds of new templates and themes to give their work a jump-start to polished perfection.

Professional Output: Your Ideas Look as Good as They AreWhen ideas look good, they get the attention they deserve, and Office 2008 for Mac delivers new tools and functionality to create great-looking charts, graphics and professional documents with ease. A key component is SmartArt Graphics, another suitewide feature providing a wide range of professionally designed graphics that can be added to any document, spreadsheet or slide show with just the click of a button.

Publishing Layout View in Word 2008 is a new specialized work space where users can simply create and edit layout-rich documents. Newsletters, fliers and brochures are a snap to design with layout tools such as Zoom Loupe and color-coded, linked text boxes to flow columns of copy between pages. Updates to Notebook Layout View will help students stay organized with quick note-taking capabilities that let them search and flag relevant information.

PowerPoint 2008 is also packed with tools that produce professional-looking results. The new Thumbnail View provides a side navigation pane that makes it easier to ensure design consistency while improving the flow of slides. The Object Palette offers quick access to shapes, art, symbols and pictures, including iPhoto images, while Dynamic Guides help users quickly align text and graphics for a crisp, clean slide design. The improved Presenter Tools in PowerPoint 2008 become even more useful, now featuring both elapsed and actual time indicators for greater control over timing and pacing. And to help share slides on-the-go, new integration with iPhoto lets users share professional presentations from a Mac to an iPod by saving as a PNG or JPG file.

Even data can impress with new graphic capabilities in Excel. Excel 2008?s Building Charts utilize the new OfficeArt graphics engine, giving users a helpful tool to create polished, modern charts and modify their look and feel with a single mouse-click.
